To answer your question, I use an iPhone to post both cash and credit prices. There is something off when you post, though. I have a screenshot of cash prices going into the credit slots, such that both cash and credit prices are cash prices---the previous poster in cash and you in credit. I sure would like figure this out. How are you reporting exactly, app or full site?

Due to those cwazy wabbits at GBO, the apps currently post credit prices (unless station is cash only) to the price lists and FSL of the full site. This will be corrected when they revamp the full site for cash & credit (date unknown). Until then, it's a mess and there is nothing we mere mortals can do about it.
